Matrix converter

The AC7 Matrix Converter is designed to lead a new age of drive performance. The AC7 incorporates innovative technology as the world's first low-voltage (230V/460V) matrix converter to directly convert input AC voltage to output AC voltage without the need for a DC Bus, according to the manufacturer.

Not only does the AC7 improve energy efficiency, but it also overcomes many problems typically associated with conventional drives, such as harmonic current distortion, line regeneration, installation space, and motor drive issues (very long cable lengths, bearing currents, and common mode currents).

Engineered Systems magazine’s May 2020 issue examines the revitalization of air-cooled chillers in data center facilities, the viability (or lack thereof) of duct systems, the impact the coronavirus is having on the built environment, and much more.
